Rust Engineer

Rust Engineer

Backend / Systems / Infrastructure

Location: Remote or hybrid: Warsaw / Kraków / Wrocław / Gdańsk
Seniority: Mid+ / Senior / Lead
Tech stack: Rust, Tokio, Axum, gRPC, PostgreSQL, Kafka, Kubernetes, OpenTelemetry

About the role

For our client, we are looking for a Rust Engineer who wants to work on a product where Rust is not used as a buzzword, but because it actually makes sense. This is not another CRUD backend rewritten in Rust just to sound modern. The team is building a performance-critical platform layer where reliability, low latency, memory safety and clean architecture really matter.

You will work on core backend and infrastructure components used in production, with real traffic, real technical constraints and real ownership. The project is especially interesting for people who enjoy problems around distributed systems, high-performance backend, event-driven architecture, observability, API design and system reliability. If you like Rust because it gives you control, safety and elegance at the same time, this role should be worth a conversation!

What you will work on

You will help design and build production-grade systems in Rust, mainly around backend, platform and infrastructure engineering.

Your work may include:

• building core services and APIs in Rust,

• designing async systems with Tokio,

• working on event-driven architecture and message processing,

• improving performance, latency and reliability,

• designing clean interfaces between services,

• working with gRPC, REST and internal APIs,

• adding observability with tracing, metrics and logs,

• profiling, benchmarking and optimizing critical parts of the system,

• participating in architecture decisions,

• reviewing code and shaping engineering standards,

• helping the team decide where Rust makes sense and where it does not.

This is a role for someone who wants to understand the system, not just close tickets.

Tech stack

The exact stack depends on the team and product area, but you can expect work with:

• Rust

• Tokio / async Rust

• Axum / Actix / Hyper / Tower

• Tonic / gRPC

• PostgreSQL

• Kafka / NATS / event-driven systems

• Docker / Kubernetes

• AWS / GCP / cloud infrastructure

• OpenTelemetry

• Prometheus / Grafana

• CI/CD

• GitHub Actions / GitLab CI
  

What we are looking for

We are looking for someone who has strong engineering fundamentals and wants to build reliable software.

You may be a good fit if you have:

• commercial or strong practical experience with Rust,

• good understanding of ownership, borrowing and lifetimes,

• experience with async Rust, preferably Tokio,

• experience building backend services or infrastructure components,

• understanding of API design, concurrency and reliability,

• ability to write clean, maintainable and tested code,

• interest in performance, observability and system design,

• pragmatic engineering mindset,

• ability to discuss trade-offs, not just follow hype.

You do not need to know every technology from the stack. We care more about strong fundamentals, curiosity and good engineering judgment than checking every box.
